Cheryl made a rare public appearance at the event today, and she looked stunning in a rock 'n' roll-style T-shirt and checked boots.

She was seen manning the stars along with This Morning host Holly, who was also at the event in east London today.

Other stars in attendance included Cheryl's former Girls Aloud bandmate Sarah Harding, who pulled a shift in the morning.

The celebrity traders ranged from Hollywood royalty Danny DeVito to home grown acting talent like Damian Lewis and even royalty as Sophie, The Countess of Wessex stopped by to offer her support.

Also on hand to raise money were the likes of Davina McCall, Fearne Cotton, Alan Carr, Penny Lancaster and Lorraine Kelly, while the world of sport was represented by Sir Alex Ferguson and Sam Allardyce.

The BCG Charity Day is held every year on September 11 in conjunction with the Cantor Fitzgerald Relief Fund, to remember the company's friends and colleagues who perished in the Twin Towers terror attacks in 2001.

Taking a more laid-back approach to fundraising was singer Tito Jackson, representing Caudwell Children, who made himself at home by leaning back in his chair, while Rod Stewart's model wife Penny Lancaster initially shunned a chair in favour of perching herself on the edge of a desk.

Penny, also representing Caudwell, later found herself a chair she liked and stretched out, resting her long legs on the desk in front of her.
